Improvement in eyeleting-machines



UNITED STATES PATENT OEETCE.

HYMEN L. LIPMAN, OF PHILADELPHIA, PENNSYLVANIA,

IMPROVEMENT lN EYELETlNG-MACHINES.

Specification forming part of Letters Patent No. 45,727, dated January 3, 1865.

To all whom it may concern Be it known that I, HYMEN L. LIPMAN, of Philadelphia, Pennsylvania, have invented certain Improvements in Eyelet-Machines; and I do hereby declare the following to be a full, clear, and exact description of thesame, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to certain improve ments, fully described hereinafter, in machines used for attaching eyelets to articles of wearing apparel.

In order to ena-ble others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying draw ings, which form a part of this specification, Figure 1 is a side view, partly iu section, of my improved eyelet machine; Fig. 2, a sectional plan view on the linel 2, Fig. l,and Figs. 3, Il, 5, and 6, dia-grams illustrating a part of my invention Similar letters referto similar parts throughout the several views.

A is thc frame of the machine, the foundation-plate a, which forms a part of the frame, being secured to a bench or table, o, and the upper surface of the latterl being represented by the line b. rlhe frame is ofthe bent form illustrated in the drawings, and terminates above iu the hollow box or casing B, and below in the projection C, which is situated at a dis tance above the bench or table b for a purpose explained hereinafter.

D and D are two rods or spindles, which pass through and are guided by openings in the lower portion, c, of the box or casing B, and by openings in a partition situated within the box, and shown by dotted lines in Fig. l. A

coiled spring, f, surrounds each spindle, and g tends to elevate the same after it has been depressed by the movement of the lever H, which is hung to a pin, h, passing through the upper end ofthe boX, and which has two arms, (shownby dotted lines), one arm for bearing ou each spindle.

In the lower end of each spindle is a hole, in which is cut an internal screw-thread, adapted to the screw-thread on the projection i on the upper end of a detachable die, the spindle D being thus provided with a detachable die, E, and the spindle D with a die, F. On the under side ofthe die E are formed cutting edges, arranged in the form of a cross, Fig. and the lower end of the die F has a projection arranged to tit into an eyelet., and a shoulder, m, for compressing the same.

A dovetailed recess is cut in the upper surface of the projection U for the reception ot the plate G, which is secured by the set-screw n, and in the upper surface of this plate is let a small strip, q, of planished brass, to receive the cutting-edges of the die E. A hole, t, passes through the plate G and projection U, this hole being cent-ral with the die F, and being countersunk or recessed at the top for the reception of the ange of the eyelet.

It should be understood that the above-described machine is designed for attaching eyelets to articles ot wearing-apparel, whether they be made of textile fabrics, leather, or guinelastic fabrics.

In using the machine the fabric is in the rst instance placed on the plate G in such a position that the point where the eyelet has to be inserted shall be directly below the die E. The latter, by operating the handle H, is then depressed, so as to make in the fabric au incision in the form of the cross, Fig. 3. Au eyelet is then placed, flange downward, in the counter-sink of the plate G immediately below the die F. The fabric (shown by the red line no) is then held up to this die, so that its projection may pass through the fabrica-t the point where it was severed by the cutting-die hl, after which the handle II is so operated as to depress the die F, thereby causing the fabric to pass over the eyelet and compressing the la'ter and securing it tirmly to the fabric.

rI'he ordinary method of securing eyelets to wearing-apparel is to lrst pierce the latter with a sharp tapering instrument, which disintegrates the bers of the fabric, distorts the latter, and makes a hole of such a character as to render the insertion of the eyelet a mattei' of dit'ticulty. rIhe whole operation of securing eyelets by the usual process demands tedious manipulation, which is to a great extent avoided by this portion of my improvement.

It will be understood that the severed por tions of the fabric do not appear when the eyelet has been secured, as they are covered by the bent portions of the eyelet when the latter is compressed.

It is not necessary that the cut in the fabric should 'in all cases be of the form illustrated in Fig. 3. In many cases the cut may be ot' the form shown in Fig. 4, or that seen in Figs. 5 or 6; or modified forms ot' these cuts may be used, according to the nature of the fabric to be operated on and the judgment of the operator. ln all cases, however, butlittle of the fabric should be cut way, the opening for the insertion of the eyelet being made for the most part by merely severing the fabric.

As eyelets of different sizes have to be operated upon, it is important that the dies E and F should admit of being removed, which can be readily accomplished in my improved machine by simply unserewing them from the spindles. It is also important, for the same reason, that the plate G should be readily detached, which can be done by simply withdrawing,` the screw n.

By arranging the projection G above the] table many articles of wearing-apparel can be operated upon which could not be reached in the absence of this projection.

I claim as my invention and desire to secure by Letters Patent* In combination with an eyelet-machine, a die which makes a crucial incision in the fab ric for the reception of the eyelet with or without a central excision ot' a part, leaving the whole or a portion ot' the material to be embraced by the flange of the eyelet, substantially as shown and described.

1n testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
